Introduction. One of the ways to improve the accuracy of manufacturing parts by cutting is related to the control of elastic deformations of the tool and the workpiece. This is particularly true for slender parts, whose stiffness law along the tool p

Introduction. Selective transfer is a typical example of the self-organization processes in tribosystems. In this case, joint surfaces of the servovite film are formed in the contact area, which changes fundamentally the friction and wear conditions.

Introduction. Many scientists in their research aimed at investigating the cutting process dynamics, the cutting system stability and forming various attracting sets of deformational displacements, consider the machine an autonomous system. In contra

High precision metal-cutting machines ensure that the programmed machine actuator trajectories correspond to the real ones. For lathes these are the trajectories of the longitudinal and transverse calipers of the system, as well as the spindle. The p

Regulations are generalized on the synergetic theory of control for the case when the paths of shaping motions have a frequency structure exceeding considerably a pass band of servomotors which control a motion of executive elements. There is shown a

The energy concept is a well-recognized approach for estimating the tool wear. The wear rate has been shown to depend on the power of irreversible transformations of the energy applied for cutting. Irreversible transformations alter the parameters of

Attention focuses here on the conversion of the trajectory of spindle-group wobble in a lathe into deformational displacement of the tool and the associated modification of the shaping trajectory. This process depends on the change in dynamic propert
